This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
RISK...Limited.
AREA...Far Northwest Arkansas and East Central Oklahoma.
ONSET...Mid Afternoon.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing.

FIRE WEATHER DANGER.
RISK...Elevated.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing.

DISCUSSION...
Elevated fire weather conditions will exist through the afternoon
hours both ahead of and behind a slow moving cold front positioned
near I-44 early this afternoon. Behind the front, northeasterly
winds will increase, with gusts in the 20 to 30 mph range, while
ahead of it, southerly winds gusting 20 to 25 mph will continue.
Relative humidities will not be as low as yesterday, but the gusty
winds will offset that, leading to rapid fire spread potential.
Conditions will improve this evening.

Isolated to scattered thunderstorms may develop mid to late
afternoon along the front, especially across portions of far
eastern Oklahoma and western Arkansas. Widespread severe weather
is not anticipated, but the strongest storms may produce hail near
the size of a quarter.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
WEDNESDAY AND THURSDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY THROUGH MONDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Low thunderstorm chances will continue through Wednesday night as
the lingering surface front lifts back north as a warm front.

More widespread shower and thunderstorm potential will arrive with
a strong upper level storm system Friday and into Friday evening.
Severe thunderstorms will be possible during this time frame, with
damaging winds likely to be the primary severe weather threat.
Locally heavy rain may also occur.

Additional strong to severe storms will be possible later Friday
night as the upper low passes, with large hail potential due to
the cold temperatures aloft. The pattern will remain active well
into next week, with additional strong to severe thunderstorm
chances beginning late Sunday and into Monday.
